Recent research found that configural information is less important for the processing of sexualized bodies than for the processing of nonsexualized bodies. The present investigation aims to expand these findings by directly manipulating configural versus analytic processing of sexualized and nonsexualized bodies. We posited that disrupting first-order relational information through scrambling should be associated with larger N170 amplitudes (scrambling effect) for nonsexualized bodies, whereas the scrambling manipulation should not modulate N170 amplitudes associated with sexualized bodies and objects. We presented images of scrambled versus intact sexualized bodies, nonsexualized bodies, and objects while the N170 was recorded. Consistent with our hypothesis, we found that the scrambling manipulation was associated with larger N170 amplitudes for nonsexualized bodies (i.e. scrambling effect), whereas no scrambling effect emerged for sexualized bodies and objects. This research is the first to show that sexualized bodies are processed analytically at a neural level. Implications for the literature in body perception and objectification will be discussed.
最近的研究发现，对于性化身体的加工而言，构型信息不如对非性化身体的加工那么重要。本研究旨在通过直接操纵性化和非性化身体的构型加工与分析加工来扩展这些发现。我们假设，通过扰乱来破坏一阶关系信息应该与非性化身体更大的N170波幅相关（扰乱效应），而扰乱操作不应调节与性化身体和物体相关的N170波幅。我们呈现了扰乱的与完整的性化身体、非性化身体及物体的图像，同时记录N170。与我们的假设一致，我们发现扰乱操作与非性化身体更大的N170波幅相关（即扰乱效应），而性化身体和物体未出现扰乱效应。本研究首次表明，性化身体在神经水平上是通过分析进行加工的。将讨论该研究对身体感知和客体化文献的意义。
